Answer: ![\dfrac{7}{132}](https://tex.z-dn.net/?f=%5Cdfrac%7B7%7D%7B132%7D)
Step-by-step explanation:
Total marbles in the jar = 8+25 = 33
Using combinations, the number of ways of choosing two marbles out of 33=
(total outcomes)
Similarly, the number of ways of choosing two red marbles =
(favorable outcomes)
Required probability = ![\dfrac{\text{favorable outcomes}}{\text{total outcomes}}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Ctext%7Bfavorable%20outcomes%7D%7D%7B%5Ctext%7Btotal%20outcomes%7D%7D)
![=\dfrac{28}{528}\\\\=\dfrac{7}{132}](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B28%7D%7B528%7D%5C%5C%5C%5C%3D%5Cdfrac%7B7%7D%7B132%7D)
hence, required probability = ![\dfrac{7}{132}](https://tex.z-dn.net/?f=%5Cdfrac%7B7%7D%7B132%7D)
Answer:
5
Step-by-step explanation:
move the terms 6x-4=16+2x
collect like terms 6x-2x=16+4
divide both sides 4x=20
x=5
